为了防止冲击地压发生,南山煤矿采用波兰PASAT-M煤体CT微震探测系统装备对盆底区18层南一段顶分层工作面进行了煤岩体应力分布原位探测,并对工作面冲击地压危险性进行了评价.研究表明,应力与地震波波速具有良好的对应关系,可以反映煤岩体中应力的分布情况;通过地震层析成像技术对波速分布情况进行反演.CT成像,以二维图像形式表征了全工作面冲击危险分布状态,进而可以快速准确判定巷道危险状态.探测和分析结果对于南山矿采取针对性解危措施提供了重要指导,使冲击地压防治工作准确.高效.“,”In order to prevent rock burst,PASAT-M media CT microquake detection system was introduced from Poland,to carry out in-situ detection of coal-rock stress distribution in a working face of Nanshan Coal Mine.The research indicates that stress has a good responding relationship with seismic wave which can reflect the distribution of coal-rock stress.This system can make inversion and CT imaging through the seismic tomography technology which can judge the tunnel hazard rapidly and accurately by two-dimensional image for burst ristk distribution.The result of detection and analysis can provide guidance for relieving targeted danger in Nanshan Coal Mine,which will be useful for precise and high-efficiency prevention of rock burst.
